Useless Box

It's not the bug, it's the feature

This wonderfully made black box might look like any old box. It even comes with an on/off switch to open the top. Convenient, right?

But this little box has a will of its own. As soon as you flick the switch, a mechanical arm emerges from the box and... flicks the switch back. And that is all this box does. Utterly useless, but in a way quite brilliant as well.

The box comes with some extra screws, bolts and a miniature screwdriver. So after you build the box from scratch, you can always keep yourself busy taking the box apart and putting it back together again, for absolutely no reason.
